Fl RE ESCAPE.

SPECIFICATION forming part of Letters Patent No. 391,561, dated October23, 18188.

Application filed June 14, 1888. Serial No. 277.046.

To aZZ whom, it may concern.-

Be it known that I, LOUIS P. SANIY, of Clements, in the county of Chaseand State of Kansas, have invented a new and Improved Fire-Escape, ofwhich the following is a full, clear and exact description.

My invention relates to a portable fire-es cape mounted on trucks andadapted to be elevated in the street; and the inventionconsists,priucipally,of three systems of lazy-tongs connected togetherand arranged to be elevated and lowered by a screw mounted in theplatform of the truck.

The invention also consists of the construction, arrangement, andcombination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of my invention. Fig. 2 is a sectional planview thereof, taken on the line 00 m of Fig. l; and Fig. 3 is a planview showing the top of the fire-escape.

A represents the main platform of a truck, mounted on axles B B andwheels 0 0. Upon the platform A is mounted another platform, D, havingscrews E at the corners for tilting it, so that the systems oflazy-tongs F F may be held in perfectly upright position or tipped fromthe street against the wall of a building.

The lazy-tongs F are mounted upon the platform D, and are united by theseries of triangles G G, a set of lazy-tongs being arranged at eachcorner of the triangle, so that each set of lazy-tongs braces theothers, and this renders the whole structure very firm and rigid whenelevated.

H is the screw for elevating the lazy-tongs, mounted in the center ofthe platform A, and I is a triangular plate attached at its corners tothe lowermost set of lazy-tongs,and formed in the center with aninternally-screw-threaded boss, J, in which the screw H works, as shown(No model.)

clearly in Fig. 1. The screw H is turned by the crankshafts K and thebeveled gears L L. (Shown clearly in Fig.1.) By turning thescrew H tolift the plate I the three sets of lazytongs will be rapidly elevated,and by reversing the screw as rapidly lowered.

At the top of the lazy-tongs F is placed the platform or cage M, onwhichpersons may step from the window of a burning building and be safelylowered to the ground by turning the shafts K; or they may descend bythe rope ladder N, suspended from the aperture 0 in the center of thecage, or they may use the lazy-tongs F as ladders and descend in thatmanner.

At the corners of the platform D are placed the steps P, by whichpersons when lowered in the cage M may conveniently descend from thecage to the platform, and thence to the street.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination, with the support D and vertical screw H, of thethree sets of united lazy-tongs F and the plate I, attached to the setsof lazy-tongs and connected to the screw H, substantially as described.

2. The three sets of united lazy-tongs F, provided at the top with thecage M, in combination with the screw H, platform D, and plate I,substantially as described.

3. The platform A,mounted on trucks, and the support or upper platform,D, having screws E, for tilting the same, in combination with thelazy-tongs F, plate I, and screw H, substantially as described.

4. The lazy-tongs F, mounted on the platform D,in combination with thescrew H, plate I, cage M, and rope ladder N, substantially as described.
